What is the key difference between mass and weight?
A) Mass is measured in Newtons
B) Weight is equal to mass times gravity
C) Weight is measured in grams or kilograms
B) Weight is equal to mass times (ACCELERATION OF) gravity
by the way A and C are just plain terribly exactly WRONG!!!
you do realize i have 1 attempt
The key difference between mass and weight is that mass is a measure of the amount of matter in an object, while weight is the force of gravity acting on an object.
A) Mass is not measured in Newtons. The unit for mass is generally grams or kilograms.
B) This statement is partially correct. Weight is indeed calculated by multiplying an object's mass by the acceleration due to gravity.
C) Weight is measured in Newtons, not grams or kilograms.
The key difference between mass and weight is that mass refers to the amount of matter an object contains, while weight is a measure of the force exerted on an object due to gravity.
To understand this concept, it is essential to know that mass is a fundamental property of an object and remains constant regardless of its location in the universe. It is typically measured in grams or kilograms. Mass tells us how much matter an object contains and is often considered as a measure of its inertia or resistance to acceleration.
On the other hand, weight is the force with which an object is attracted towards the center of the Earth or any other celestial body. Weight depends on both mass and the acceleration due to gravity. The weight of an object can vary depending on its location in the universe because the acceleration due to gravity may differ.
To calculate weight, we use the formula weight = mass × acceleration due to gravity. The acceleration due to gravity on Earth is approximately 9.8 m/s^2. Therefore, weight is commonly measured in units such as Newtons, where 1 Newton is equal to 1 kilogram multiplied by the acceleration due to gravity.
Considering the options provided, option B) "Weight is equal to mass times gravity" correctly describes the relationship between weight and mass. Option A) "Mass is measured in Newtons" is incorrect because mass is measured in grams or kilograms. Option C) "Weight is measured in grams or kilograms" is also incorrect since weight is measured using units such as Newtons.
